what does the word 'orthodoxies' mean

i saw a recent interview with a conservative mp here in england, on youtube..and the mp was saying that ''conservatives must reject liberal orthodoxies?'' and i was wondering what was meant by that statement?

because i am on benefits for disablements i have, and i was fearing does that statement mean they want to do away with the welfare system, i would be against that obviously, because i rely on the welfare system because i am genuinly have disablements..and i think the welfare system should exist for those who are genuinly disabled?

anyway can anyone explain what this mp possibly meant by this statement '' conservatives must reject liberal orthodoxies? ''

thankyou.
